   SHARED var1[, var2[, ...] ]
   SHARED "string1"[, "string2"[, ...] ]

This keyword sets up a list of variables of a procedure that can be accessed from absolutely anywhere in your program.

There is a facility of using strings in procedure definitions. As with disc names, the “wild card” characters * and ? can also be included. In this case, the * character is used to mean “match this with any list of characters in the variable name, until the next control character is reached”, and the ? character means “match this with any single character in the variable name”.

GLOBAL or SHARED should be employed before the first use of the variable. Only strings may be used for this technique.

  SHARED test
  SHARED "a*", b, "*c"
